ably fixed to walls of said cabs. The result of this condition was that engineers and firemen frequently complained that the rough riding characteristics of the locomotives sub-k jected them to verylgreat discomfort and eiiicient performance of their To remedy the situation referred to,` we have devised the resilient seat or stool disclosed herein which, because of its use and surroundings 1s heavily constructed, preferahly of metal, and comprises, brieliy stated, a fixed frame which rests upon the floor of the cab, and a movable seat supporting frame yielda-bly connected to said fixed. frame by means of coil springs or other suitable yieldable means. T he movable frame referred to is suitably guided by portions of said xed frame and said movable frame is provided with a foot rest which moves therewith. y

YWhen seats or stools constructed in accordance with our invention are employed in the cabs of locomotives, it has been found that the engineers and firemen are made much more comfortable while at work, hence they are able to perform their duties in a much more efficient manner thanwhen the rigid seats formerly employed were used by them.

ignates our Vimprovedresilient stool generally, said resilient stool comprising a. fixed for vertical movement by said fixed frame 1.

Mounted at the upper portion of the movable frame 2 is a seat 3 which is preferably, though not necessarily, upholstered or cushioned to rencter same comfortable to the user of the stoo Y The fixed frame l rests upon the floor of the locomotive cab or other compartment wherein the improved stool is used' and so that same may have the required stability to withstand` swaying of the locomotive cab when the stool is used for that purpose, we provide the side rails 4 at the bottom of the fixed frame 1- with inwardly projected and horizontally disposed flanges 5 which contact with the ioor. The fixed frame 1, which is preferably rectangular` in cross-section, includes a plurality of vertically disposed cornermembers 6,,said corner members being preferably formed integral with the side rails 4 at-the bottom of said lixed frame. l

Extended forwardly from the oppositel disposed vertical members 6, of the fixed framel is a pair of extensions 7, said extensions 7 beinglprovided with inwardly projected and horizontally disposed yianges 8 (Fig. 1). Fixed to the flanges 8 of the extensions by means lofbolts or other suitable fastening devices 9 is a crossbar 10.7,'l`heV cross bar 10 is extended Ytransversely ofthe bers 6 at the rear of the fixed frame 1 is al pair of extensions 1l resembling the extensions Z already referred to, ,said extensions 11 being provided with inwardly' extended and horizontally disposed flanges l2 to which a cross bar 13 is secured by bolts or other fastening devices. ,The crossbar 13 extendsV transversely of the fixed frame 1 at the rear thereof and said bar 13 serves to secure the oppositeily disposed Vvertical members 6 at the rear of the fixed frame together. At the bottom of the lixedframe the side rails 4 are tied together by bars 14 which are securedat their opposite ends by means of bolts,rfor instance, to said side rails and extend transversely of said fixed frame.

Referring now to the movable frame 2, said frame includes a plurality of corner 5 members 15 which extend downwardly from the seat 3. From the lower edge of the seat 3 to the points 15 spaced downwardly from said lower edge of the seat (Fig. 2) the downwardly extended members of the movable frame are L-shaped in cross section as shown clearly in Fig. These L-shaped portions of said members 15 embrace the upper portions of the vertical members G of the fixed frame, that is to say the inner angular faces if said L-shaped portions contact with side and edge faces of said members 6 so that while the movable frame 2 is freely movable in a vertical direction with respect to the members 6 of the fixed frame, said movable frame inay not move horizontally with respect to said members G of said fixed frame, hence the movable frame is positively guided by the members 6 of the fixed frame. At the lower portions of the members 15 of the movable frame said members are provided with channel portions 1G, which latter portions embrace the vertical members 6 of the fixed frame at the lower portions thereof. The inner faces of the channel portions 16 refer- 3o red to contact with the inner faces and edge faces of the vertical members 6 of the fixed frame hence said channel portions serve to aid in permitting vertical movement of the movable frame 2 while said channel portions assist in preventing horizontal movements of said frame. The members 15 of the movable frame are tied together to add rigidity to the frame structure by means of a plurality of bars 17 and a plurality of bars 18 extended transversely of the movable frame at the upper and lower portions respectively thereof.

Arranged at the front of the stool A is a plurality of expansible coil 4:springs 19, the upper end of each of said coil springs being l attached to an eye forming a portion of a bolt 20, secured to the bar 10 at the front of the fixed frame 1 and the lower portion of each of said coil springs being attached to a similar bolt secured to the particular bar of the plu- 5o rality of bars 18 which is located at the front of the movable frame. The bar 18 to which the lower ends of the coil springs 19 are attached is located in approximate vertical alinement with the bar 10. At the rear of the l stool we provide a secondV plurality of coil springs 21, each coil spring of the last mentioned plurality of coil springs being attached at its upper end to the eye portion of a bolt secured to the bar 13 at the rear of the fixed 6o frame of the stool'and the lower end of each of said coil springs being attached by means of a bolt having an eye portion, to the particular bar of the plurality of bars 18 which is located at the rear of the movable frame la of the stool.

Secured by means of bolts or other suitable fastening devices to the vertical members 15 of the movable frame 2 which are located at the front of the stool is a pair of oppositely disposed L-shaped brackets 22. The vertically extended legs of the L-shapcd brackets are each provided with a plurality of apertures 23 as shown clearly in Figs 1 and 2.

24 designates a foot rest which is pivotally attached to the opp-ositoly disposed L-shaped brackets 23 by means of a shaft 25, said foot rest at its opposite ends being provi-ded with L-shaped elements 26 which are secured by means of bolts 27 to said foot rest. The shaft 25 referred to is supported in a horizontally alined pair of the apertures 28 formed in the oppositely disposed L-shaped members 22 and said shaft passes through apertures formed through the L-shaped elements 26 at the rear portions thereof so as to pivotally support said foot rest, and said L-shaped elements 26 are each provided with a stop member 28 forme-d thereon adapted to contact with the adjacent L-shaped bracket 23 whereby said foot rest may be maintained in a horizontal position,

ln the use of an improved resilient stool it is plain that shocks resulting from uneven riding of the locomotive in the cab of which the stool is used will be absorbed by the coil springs 19 and 21, the movable frame of the stool, together with the seat 3, and foot rest 2&1, moving with respect to the fixed frame of the stool. lt is also obvious because of the construction of the stool that the stability thereof will be maintained at all times when same is in use in the cab of a locomotive, and that its durable structure will withstand the rought usage to which it will be subjected.

If desired, we may provide our improved resilient stool with a removable back rest 30 and to the end that same may be readily detached from the stool we attach a pair of supporting devices 31 to the vertically disposed members 15 of the movable frame of the stool, said supporting devices being each provided with a vertically extended portion 32. Fixed to the back rest 30 is a pair of members 33, each of which is provided with a lower portion provided with a recess or socket 34. To attach the back rest 30 to the stool, said back rest is moved to a position where the vertically extended portions 32 are extended into the recesses or sockets .34 at the lower ends of the members 83 secured to said back rest whereby said back rest will be maintained in the position in which same is shown in Figs. 1 and 2.
